 Extension modules
Apart from the standard communication ports on a CPU module, the CPU module is equipped with I/O
functions. Refer to section 1.1.3 for a selection of extension modules. You can find a suitable extension
module according to your needs.
The following lists the limits for setting up a common framework of the DVP-SV3/SX3 PLC system. Exceeding
the first three limits causes the PLC to send an error message.
Limit 1: The maximum number of digital I/O points is 512 (256 inputs and 256 outputs). The built-in digital I/O
points of the CPU module are included. (If DI points are 262, and DO points are 60, that means the DI
points exceed the limit range.)
Limit 2: On the right side of the PLC CPU, you can connect up to 8 modules including analog I/O modules,
temperature measurement modules, positioning modules, communication modules.
Limit 3: On the left side of the PLC CPU, you can connect up to 8 modules including high-speed analog I/O
modules, high-speed load cell modules, high-speed communication modules.
Limit 4: The maximum power consumption of CPU module and extension module should be within the range
of what a CPU module or a power module can supply. Refer to section 4.2.5.4 for the maximum power
consumption of modules.
Limit 5: Up to 14 right-side extension modules can be connected to a DVP slim type PLC CPU. The input point
starts from X20 and output point starts from Y20. Refer to the combination example below.
